About this study

PALLSOFT is a randomized, open-label, non-inferiority phase III, multicenter, national trial that will investigate whether the patient-reported symptomatic effect of palliative radiotherapy delivered in 1-2 fractions is non-inferior to palliative radiotherapy delivered in five fractions in patients with pelvic soft tissue tumors from either gastrointestinal, urological or gynecological cancer. Health-related quality of life, toxicities, survival and prognostic and predictive biomarkers will be assessed as secondary and explorative endpoints.

Read the detailed description

Studies and clinical practice have proven palliative radiotherapy to provide efficient symptom relief in patients with symptomatic pelvic soft tissue tumors. However, studies are mainly retrospective, are difficult to compare due to a variety of radiotherapy fractionation schedules used, and lack data on patient-reported quality of life. Consequently, no recommended standard of care is established, and several schedules are employed with variations in both number of fractions and total radiation dose (measured in Gray=Gy). Given the limited life expectancy of palliative patients, a short-course radiotherapy schedule would be preferable provided efficient symptom relief and good health-related quality of life.

PALLSOFT is a national, randomized, non-inferiority study that will investigate whether the symptomatic effect of a short-course radiotherapy schedule of 8 Gy x 1-2 is non-inferior to a more prolonged schedule of 5 Gy x 5. The study will include patients with symptomatic pelvic soft tissue tumors from either gastrointestinal, urological or gynecological cancer. Patients will defined a target symptom from 5 predefined cathegories (pain, bleeding, bowel/lower urinary tract/vaginal dysfunction), and change in symptom intensity will be assessed, as well as overall toxicities, quality of life and survival. Prognostic and predictive biomarkers will be explores, the latter with particular emphasis on the significance of tumor hypoxia in palliative radiotherapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient-reported symptomatic effect

    Establish whether 1-2 fractions of 8 Gy is non-inferior to 5 fractions of 5 Gy with regards to target symptom effect assessed by change in NRS 0-10 (Numerical Rating Scale) from baseline

    Measured: 12 weeks

Secondary outcomes (2)

  1. Physician-reported toxicities

    Establish whether 1-2 fractions of 8 Gy is non-inferior to 5 fractions of 5 Gy with regards to bladder and bowel toxicities assessed by CTCAE

    Measured: 52 weeks

  2. Survival

    Establish whether 1-2 fractions of 8 Gy is non-inferior to 5 fractions of 5 Gy with regards to overall survival

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Palliative radiotherapy in people with Gastrointestinal Cancer and Urologic Cancer, run by Sykehuset Telemark at 11 sites in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Kjersti Skipar, MD (+47 98444114, kjeski@sthf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient-reported symptomatic effect (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06398314, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2025; AzTrials last refreshed its copy on 7 Nov 2026.
